Thanks again Palat, you're too kind. That paint colour sheet is just what I needed. And thanks MuscleCarFreak, it wasn't easy modelling the bumper from photos so you're probably right about the step/pointy bit position needing to be a bit higher up. On the owners' club website someone pointed out that it wasn't quite right too. When I get time I'll have another look at it, just for you
In the meantime, here's a view of the rear-end, painted black with the 'stripe delete' option.
